My buddy Scott sent me this on Facebook the other day. If you’re a Mac user, bookmark this post and refer back to it next time your Mac starts acting funny. This could save you a trip to the service department at the Apple Store, and it might even prevent unnecessary service costs. Enjoy!

I had something interesting happen to me right before a show the other night and thought it might be something you could pass on to your loyal readers.

Something confused the FW bus on the 24″ iMac I use to run backing tracks for theatrical productions (a long Logic session running solely audio, no VI’s or plugs). Basically the iMac couldn’t ‘see’ the audio interface or external HD, but was still providing power to the devices. We noticed the problem at the 2-minute call (!) and I did a quick diagnosis and narrowed it down to the FW bus.

Something similar happened to me in my home setup up in Fort Wayne one night after an inadvertent hot-swap snafu. I was able to correct the issue by doing a hard reset of the PRAM and NVRAM. I would have done it immediately at the show but couldn’t remember the keystroke sequence and didn’t have time to get online and find out (we played Act I sans tracks). At intermission I did a quick Google and found the article on Apple support:

The steps above immediately fixed the problem. No clue what caused it – we’re on UPS’s and have pretty clean power, so I’m thinking someone popped a cable or something ). This is a handy trick for those times that a FW bus becomes ‘confused’ or scrambled. It can save a trip to the Apple Store and somebody saying you need a new logic board when you don’t. And with all the FW drives & interfaces out there it’s probably happening to others.

Be sure to thank Scott for this great little pearl of wisdom by leaving a comment. 🙂
